IMPROVEMENT IN BELL-PULLS.

Specification forming part of Letters Patent No. 163,741, dated May 25, 1875; application filed December 28, 1874.

it, reference being bad to the accompanying drawings, which form part of this specification, in which Figure 1 is a side elevation; Fig. 2, top view of wheel and handle; Fig. 3, rear elevation of faceplate; Fig. 4, rear elevation of wheel-sections and handle; Fig. 5, front elevation of bell-pull; Fig. 6, vertical section of face-plate and Wheel.

The invention has relation to bell-pulls; and consists, first, in forming guides or ways on the inside of the face-plate on both sides of the opening through which the wheel works,

said ways holding the loop, which is thus rendered adaptable to both right and left hand bells; second, in certain details of construction hereinafter fully set forth.

Referring to the accompanying drawing, A represents the face-plate, which may be ornamented in any suitable manner; and a, an opening therein, through which the wheel or segment works. a a are ways on the inner side of the opening a, and on both sides thereof; and a a? are cars located beneath said ways, and afl'ordin g bearings for the shaft of the Wheel. B is the wheel, cast in two sections B and B The section B is formed with the vertical flange 12, forming a periphery, which serves as a face or edge for the front of the wheel, and also with the boss b segmental flange b and handle b. The section B has a central opening, b for the passage of the boss and is also furnished with a segmental flange, 1) similar to b. When the parts 13 and B are brought together, being held thus by a rivet or screw, b the flanges b b form a groove for holding the chain 0. d is the shaft of the wheel B, having bearings in the ears-0t a and e is a T-slot formed in the flanges b b for the purpose of holding the end of said chain 0. The chain 0 is secured in said slot by passing one of its links 0 down therein, and giving it a quarter-turn, which will prevent its coming out. E is the loop, fitting in the ways a ct on either side of the opening a, being removable from one side of said opening to the other, so as to render it adaptable to right and left hand bells. f is a sheave or pulley in said loop, over which passes the chain 0.

The periphery or face b of the section B should be made with a line, b to correspond with the line between the sections, and so preserve the symmetry of the said wheel.

What I claim as my invention is- 1. A bell-pull face-plate, A, having ways or lugs a a on each side of the opening a for holding the loop E, substantially as shown and described.

2. In combination with the plate A, having the ways a a the removable adjustable loop E, substantially as shown and set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of December, 1874.
